I can't believe what we're seeing out of Marion and Jasper. Can somebody more familiar with Iowa than I am explain what it is about those counties relative to the rest of the south-and-east-of-Des Moines part of the state?
Seriously. Not only why is Santorum doing so well, but also Romney doing particularly poor there?
I assume both have plenty Evangelicals. Huckabee won them by about 50% in 2008.
The last exit polls showed Santorum leading among Evangelicals by a considerable margin, so I imagine your supposition is correct.
